NWS Says Heavy Rainfall With Isolated Flash Flooding In CNY Today 8-21

We're expecting clusters of storms to move through CNY, and some could turn severe with damaging winds, heavy rainfall, and isolated flash flooding.

According to the National Weather Service (NWS) out of Binghamton, there is the potential for strong to severe thunderstorms as well as locally heavy rainfall that could result in isolated urban/small stream flooding.

...SCATTERED SEVERE THUNDERSTORMS POSSIBLE TODAY...

Clusters of thunderstorms are expected to cross the area this morning through the afternoon. A few of the storms could become severe with damaging winds, locally heavy rainfall, and small hail. Isolated flash flooding will be possible in poor drainage locations such as urban areas, and where multiple thunderstorms occur.

The Storm Prediction Center includes our area in a marginal to slight risk for severe thunderstorms today, with the somewhat higher threat tilted towards Northeast
PA and along-east of I-88 in Central NY. Pockets of damaging wind will be the main concern with the storms today, though at least some small hail could also occur.
